Hello Mal and LF group,

I was going to post something about the conditions on Tuesday evening
(13th into 14th Nov) so Mal's post is an appropriate place to do it.


I understand that some excellent T/A conditions were experienced that
night, with Finbar working a WE2 station and I believe Mal himself may
have worked VE1ZZ also. I had to go to work for a night shift so missed
the late night excitement.

Closer to home, earlier in the evening, Finbar and I had a long QSO in
which we repeated a previous QRP experiment (the one reported in this
month's RadCom). This time Finbar was able to reduce TX power in
stages down through 5W, 2.5W, 1W, 500mW, 200mW, 100mW, 50mW, 20mW and
finally 10mW.

At each step I could read his CW by ear and at several of them he sent
a 4-figure number for me to verify. At the final level of 10mW (TX
power!!) I took a few minutes, riding the QSB and piecing together
fragments of CW from the noise, but finally got the 4 numbers
correctly. This is a fantastic "miles per watt" even at 10mW. Imagine
what the "miles per watts ERP" might be?

Earlier in the QSO I'd had to break off for a few minutes and left my
audio recorder running. I listened back to the file yesterday while
driving and heard Dave G3YMC call Finbar! This is the first time I've
heard Dave's 5mW ERP and it was readable by ear! Finbar failed to hear
Dave's call though, which I'm sure is a disappointment to him, and to
Dave. I don't know if this was a fleeting opening as no more was heard
from Dave later in the evening.



The conditions were superb, but it's only in hindsight that this
becomes apparent, as they subside back to "normal" for a few days. 


Well done everyone concerned and let's hope for more.
